SPECIFICATION forming part of Letters Patent No. 489,864, dated January10, 18'93.

Application tiled March 14:, 1892. Serial No. l124.901. (No model.)

To @ZZ whom, t may concern:

Be it known that I, FRED H. HARDMAN, a citizen of the United States,residing at Beverly, in the county of Essex and State of Massachusetts,haveinvented new and useful Improvements in Shank-Buttons, of which thefollowing is a specification.

This invention relates to improvements in the construction of what isknown as shankbuttons, a most common type of which is the shoe button,the invention particularly pertaining to the eye-shank, the object ofthe invention being to so improve the form of the eye-shank that it willof itself be of unusually simple construction and capable of easyproduction and furthermore be susceptible of the most efficientengagement with the papier mach or other material from which the buttonhead is molded.

The invention consists of the shoe button having its eye-shank formed ashereinafter fully described and set forth in the claim.

Referring to the accompanying drawings in which the shoe button isillustrated on an enlarged scale, Figurel isa perspective view of theeye-shank the head being indicated by dotted lines. Fig. 2 is a Viewatwise of the eye-shank, the head being in section. Fig. 3 isa'sect-ional view of the button taken at right angles to Fig. 2. Eig. 4is a plan View of the eye-shank the head being shown in dotted lines.

The eye-shank is formed of a piece of wire intermediately bent to formthe eye-loop, a, as usual, and has its extremities brought and extendedalong together substantially as shown in the drawings. The saidextremities have the metal forming the same displaced outwardly to formflattened portions l), h, of greater Width than thickness which are{iat-- Wise of the eye-shank atashort distance from their ends, whichmay be done by swaging or die-pressing, the metal being outwardlydisplaced and bulged edgewise of the eye-shank as seen at CZ. As clearlyshown there are formed shoulders, ff, intermediate between saidflattened portions and the extreme ends of the Wire,tl1e flattened facesbeing at opposite sides which are atwise of the eyeshank and also theshoulders or enlargements at the outwardly displaced portions, CZ d, atright angles thereto or edge-wise of the eye-shank, all to the end ofaffording most efficient and satisfactory engagements between the moldedpapier mache button-head and the embedded portion of the eye-shank. Thisform of eyeshank may moreover be cheaply and rapidly produced bymechanism of unusualsimplicity.

Having thus described my invention What I claim and desire to secure byLetters Patent A shoe-button having its eye-shank formed of a piece ofwire with its extremities brought into juxtaposition and the metal ofsaid eX- treinities displaced outwardly to form attened portions ofgreater width than the diameter of the wire of the shank, forminganchoring shoulders intermediate the said flattened portions and theeXtreme ends of the Wire, which latter are substantially uniform withthe diameter of the wire, substantially as described.

FRED H. HARDMAN.
